I read Fujita Susumu's blog. He is president of "Cyber Agent"it's his company. He said "I don't know what is the secret to sale, but I know that who is good sallesman.This is a persistent salesman. Because, if sallesman is reserved, I woudn't contact him again. If sallesman is persistent, I would contact him."
I think it is refer to love. Passive is not good. Active is so good.
